So today I noticed that one of my mp60's is not running and it is emitting a high pitched beeping noise. The LED in the control knob is also blinking on with the beeping. None of the buttons are responding. I tried unplugging it both the wet side and dry side seem to be able to move freely. I plugged in the other power supply from my second mp60 and it did the same thing. Could the drivers be shot? Does anyone have experience with this?
